For report - NCEE 2009-4079 Accommodations for English Language Learner Students: The Effect of Linguistic Modification of Math Test Item Sets http://ies.ed.gov/ncee/edlabs/projects/project.asp?ProjectID=92
This file contains data from a study that analyzed the impact of middle school math assessment accommodations on standardized math test items for English Language learners. The study examined students' performance on two sets of math items--both the originally worded items and those that had been modified. Researchers analyzed results from three subgroups of students--English learners (EL), non-English language arts proficient (NEP), and English language arts proficient (EP) students. The final analytic sample for the study consisted of 4,617 grade 7 and 8 students from the 13 participating schools.
